Dive into this guide to ensure your pea puffer fish swim happily alongside their ideal companions, fostering a lively and harmonious aquatic haven!

Pea Puffer Fish Behavior

Pea puffers, also known as Indian pea puffers or freshwater pea puffers, are intelligent, territorial, and often aggressive toward tank mates, especially those with long fins or a slow swimming style. Despite their small size (about 1 inch), they pack a punch of personality. They prefer having plenty of hiding spots and love exploring their environment. Understanding the pea puffer's natural habitat - shallow, plant-dense streams in India and surrounding regions - is key to replicating their comfort zone in a home setup.

They are inquisitive and often display unique individual behaviors. Some may tolerate specific tank mates, while others prefer to be solitary. They are best kept in species-only setups unless carefully matched with compatible pea puffer tank mates. Pea puffer freshwater tanks need careful planning and ongoing observation.

1. Otocinclus Catfish

Otocinclus catfish are one of the best tank mates for pea puffers. They are peaceful, small, and primarily stay on surfaces cleaning algae. Since they are non-aggressive and don’t compete for space, pea puffers often ignore them. Their small size (1.5-2 inches) and fast swimming ability allow them to avoid unwanted attention.

Why it works: Otos stick to themselves, clean your tank, and are fast enough to avoid conflicts. Keep them in small groups of 4-6. Provide plenty of algae or supplement their diet with algae wafers to keep them healthy in a pea puffer aquarium.

2. Danios

Danios, particularly Zebra Danios, are quick, hardy, and tend to school together. Their speed makes them less likely to be targeted by pea puffers, and their active behavior can even help distract the puffers from bullying other tank mates.

Why it works: Their constant motion and tendency to stay in the middle to upper regions of the tank make them compatible with pea puffers. Danios also tolerate a range of water parameters, making them easy to care for in diverse freshwater setups.

3. Rasbora

Rasboras like the Harlequin Rasbora or Chili Rasbora are peaceful, small, and schooling fish. Their calm nature and small size make them suitable companions in a pea puffer aquarium setup, especially in larger tanks where territories can be established.

Why it works: They are non-intrusive, fast-moving, and rarely provoke aggressive behavior in pea puffers. In a well-planted tank with open swimming areas, Rasboras can thrive alongside pea puffers without competing for food or territory.

4. White Cloud Minnow

White Cloud Mountain Minnows thrive in cooler water temperatures, but they are very adaptable and can be good tank mates for pea puffers in mid-range temperatures. They are peaceful and active swimmers.

Why it works: Hardy, fast, and peaceful—these minnows can handle the occasional chase without stress, making them good contenders. White Clouds also enjoy schooling and do well in groups of 5 or more, which adds dynamic movement to your tank.

5. Small Tetras

Tetras like Ember Tetras or Green Neon Tetras are visually striking and active swimmers. In a pea puffer tank, they can add movement and color without creating aggression, especially if kept in larger schools.

Why it works: Schooling behavior reduces the chance of a single fish being targeted. Their speed and agility also offer protection. Additionally, their preference for the middle to upper levels of the tank helps them stay out of a puffer’s path.

6. Freshwater Shrimp

Can pea puffers live with shrimp? It depends on your goals. While some hobbyists have success with ghost shrimp or adult Amano shrimp, most pea puffers will nip or hunt smaller species like cherry shrimp. A heavily planted tank and plenty of hiding spaces are essential if you try this combination.

Why it works (sometimes): Large, quick, or well-camouflaged shrimp may coexist, especially in large tanks with visual barriers. Expect some losses, and don’t mix shrimp if you’re breeding them. Freshwater shrimp should be viewed as experimental tank mates in a pea puffer freshwater setup.

7. Freshwater Snails

Though they may not be true tank "mates," freshwater snails like Nerite Snails or Malaysian Trumpet Snails are often added to help control algae in aquariums. However, this introduces a common question: do pea puffers eat snails? The answer is yes - pea puffers are natural snail hunters. In the wild, snails are a staple part of their diet, and in captivity, they often pursue even decorative snails out of curiosity or instinct. They may not always consume the entire snail, but they enjoy biting and breaking the shells, especially with smaller or softer species like bladder or ramshorn snails.

Why it works (temporarily): Snails can be seen as food or toys. Add them only if you accept their potential loss. Some keepers use snails as enrichment for their puffers. Bladder snails and ramshorn snails are often used as live feeders to stimulate natural hunting behavior.

 

Tips to Introduce New Pea Puffer Tank Mates

1. Use a large tank (at least 10 gallons for a trio of puffers and more for community setups).
2. Add tank mates first to reduce territorial behavior.
3. Provide visual breaks like plants, driftwood, and caves.
4. Feed well to reduce food competition.
5. Observe daily for signs of aggression or stress.
6. Quarantine all new tank mates to prevent disease.
7. Choose fast, non-aggressive species with small body profiles.

These steps are crucial when deciding which tank mates for pea puffers can coexist long-term.

Set Up An Ideal Pea Puffer Fish Tank

A proper pea puffer tank should mimic their natural environment:

• Tank size: Minimum 10 gallons for 1-3 pea puffers, more if including tank mates.
• Water temperature: 74–82°F
• pH range: 6.5–7.5
• Water hardness: Soft to moderately hard (5–15 dGH)
• Filtration: Gentle flow with sponge filters to avoid stressing small fish
• Substrate & decor: Fine gravel or sand, dense planting, hiding spots, leaf litter for tannins
• Lighting: Moderate to low, to encourage aquatic plant growth and reduce stress
• Diet: Live/frozen foods like bloodworms, brine shrimp, snails, and daphnia. Pea puffers rarely accept dry food, so a varied, protein-rich diet is essential.

Creating a well-planted, stable, and enriched pea puffer freshwater setup increases the chances of success with peaceful community living. Visit this blog for more information on How to Care for Pea Puffer Fish.

Conclusion

Pea puffers may be small, but their strong personalities require thoughtful planning when choosing tank mates. While not all freshwater puffer fish tank mates will work, fish like Otocinclus, Danios, and Rasboras show the best potential for coexistence. Always prioritize the puffer's needs and keep a close eye on behavior. With careful selection and setup, your pea puffer aquarium can be both lively and peaceful. Matching tank mates for pea puffers requires balancing temperament, speed, and environment.

Pea Puffer Tank Mates Frequently Asked Questions (FAQs)

Can Pea Puffer live alone?

Yes, pea puffers can live alone and may even prefer it in smaller setups. A single freshwater pea puffer in a well-planted 5–10 gallon tank can thrive if given proper care and enrichment. Solo setups reduce aggression and make feeding and maintenance easier.

Can Pea Puffer live with Guppies?

Generally, no. Guppies have long flowing fins that can attract the attention of pea puffers. These fins are tempting targets, and guppies are often nipped at, leading to stress or injury. If attempted, ensure there are lots of hiding spaces and monitor closely - but it's not recommended.

Can Pea Puffers live with Bettas?

It is not recommended. Both species can be territorial and aggressive. The likelihood of fin-nipping and fights is high, especially in smaller tanks. Pea puffers are curious and may constantly harass bettas, even in planted tanks. It's best to keep them apart for the safety of both fish and to maintain harmony in your aquarium.
